tion, reference being had to the accompany in g drawings, and to theletters and figures of reference marked thereon.

The object of my invention is to provide a valve for regulating thesupply of water to a tank automatically, and so that, when the waterinthe tank reaches a given point the water will drain therefrom, and whenbelow that point the water will enter the same, substantially ashereinafter fullydescribed, and as illustrated in the drawings, in whichFigure 1 is a side elevation of my invention showing a portion of areturn tank to which it is applied. Fig. 2 shows a side elevation of thesame on a slightly enlarged scale. Fig. 3 is a longitudinal verticalcentral section of the valve. Fig. 4: is a detail view of the upper endportion of the valve-spindle of the exhaust valve of my invention,andFig. 5 is a detail view of the block against which the float leverbears.

In the drawings A represents a suitable tank having a supply pipe a,theend of which entering said tank is, preferably, provided'with lateralarms, each of which has a longitudinally arranged series of perforationsthrough which the water issues into the tank, or out through which theexcess water drains, as will hereinafter more fully appear. The heightto which the water rises in the tank is regulated by means of a suitablefloat B, through the medium of my improved regulating valve to whichsaid float is connected by an arm, sub:

stantially as shown.

One end of my improved regulating valve is fastened in and to the headof thetank, preferably, on a plane indicating the low water mark in thetank at which it would be desirable to open said valve so as, toincrease preferably, screw threaded as far as the circumferential flangec. This screwthreaded part is passed through a suitable opening in thehead of the tank until stopped by said flange c, whereupon a nut b isscrewed over said end to clamp the casing of the valve in place. Iprefer to interpose a suitable packing ring 1) between said nut and theportion of the tank it would otherwise-come in contact with, so as tomake a perfectly water tight globe-shaped inner part. of the portion Dis provided with a vertically projecting inlet stub a, to which the mainsupply pipe (1 is coupled,'and diametrically opposite this stub a, is ahandhole which is normally closed by the cover e. The waist'of thisintermediate portion D is less in diameter than the remainder of itslength so as to provide a Valveseat f against which the inlet valve Gnormally presses. The outer part of this intermediate portion D isprovided with a downwardly projecting stub D to which the outer end ofthe tank supply pipe at is connected. The outer portion E of the casingof the valve is shaped'so'as to form practically a pipe angle, the innerflanged end edges of which are suitably secured to the correspondinglyshaped outer end edges of the intermediate portion D. The'outer etid ordischarge end of the portion E is, preferably, also screw threaded so asto be coupled to the pipe E leadingto a' drain or sewer. Just inside theplane of the downwardly extending discharge end of the portion E, it isprovided with a suitable partition in which is a contracted opening, theinner annular edges of which are shaped as shown to provide a seat 2'for the discharge valve H.

Valve H is made of any suitable material, and'is securely fastenedto theouter end, of the horizontal spindle K, the outer end por- ICO tion ofwhich is provided witha circumferentialtlange 2 which bears outwardagainst said valve H, and between which and a nuth said valve issecured. The outer extremity of this spindle K is smooth and extendsthrough and moves in a suitable guide'opening in a bridge spanning theouter end of the contracted opening normally closed by valve H. The partof the spindle K between the flange 2 and the tank, is of the samediameter, and extends centrally through the casing, to and through thevalve G and the hollow stem L to the outer end of which said inner valveG is secured. This hollow stem L is provided with a circumferentialflange near its outer end against which the valve G is placed andsecured by means of a nut m; a washer -n being, preferably, placedbetween the said valve G and nut m to prevent abrasion of the valve.

The valves G and H are normally kept in their relative positions againsttheir respective seats, by means of the expansion coil spring R,interposed between them and surrounding the spindle K, and having itsends pressing against said valves in opposite (lirections, as shown inthe drawings.

The inner ends of both the stem L and the spindle K extend into the tankbeyond the inner extremity of the casing of the valve, and the spindle Kextends a suitable distance farther into the tank than the end of thehollow stem through which it passes. Now the obvious object is to drawvalve H away from its seat when thewaterin thetankis too high,

additional water to the tank as needed.

so as to drain the surplus water therefrom into the sewer; and itsobject is likewise to push the valve G away from its seat, when thewater in the tank is low, so as to supply To accomplish this result Iprovide an L-shaped lever N,which is fulcrumed in the arms o projectingupward from a collar 0 screwed onto the inner screw-threaded end of thecasing inside the tank. The vertical arm of this lever extends downwardfrom its fulcrum into a longitudinal slot intersecting the inner end ofthe spindle K diametrically and extending from its inner extremity to apoint inside of theinner end of the stem L, as shown. I place on bothsides of the vertical arm of lever N I-shaped blocks 9 and 10,respectively, the longitudinal webs of said blocks resting in the slots,and the heads thereof coming outside and bearing against thecircumference of the spindle. The block 9 is secured in place by thelock-nuts 7 and 8, and the block 10 normally rests against the innerannular edges of the stem L. One of the peculiarities of thisconstruction is that it enables the float in the tank to be given alimited movement without affecting the valve, thus enabling me toprovide for a high water and low water danger mark between which thefloat may move without causing the water to enter the tank or dischargetherefrom. Now the inner end of the horizontal arm of the lever N 1ssuitably secured to the opposite end of the arm attached to the float B,and according as this arm moves, the lever N is operated so that itsvertical arm will bear outward against the stem L to open the valve Gand thereby increase the supply of water to the tank, or will draw thevalve H inward through the medium of the spindle K so as to exhaust thesurplus water from the tank into the sewer.

What I claim as new is- 1. The combination with a water tank, and a pipedischarging into the same, of a suitable float on the end of an arm, alever to which said arm is connected, a valve closing the inlet leadingto the pipe which discharges into said tank, and a valve closing a drainoutlet out through which the backrush of water from the tank can drain,said inlet valve being above the drain valve and having a hollow stemarising therefrom, and said drain valve having a vertical spindlearising therefrom to and above the hollow stem of the inlet valve, saidvalves moving in opposite directions when closing and moved toward eachother according to the movement of said lever in order to open.

2. The combination with a tank, and a pipe discharging into the same, ofa float, a lever to which the said float is connected by a suitable arm,a valve G closing the inlet to said pipe, a sleeve stem arisingtherefrom, a valve H closing said drain pipe, a spindle arisingtherefrom and passing through said sleeve stem and an expansion springplaced between and bearing against said valves, and a suitable hollowcasting having an inlet above valve G, a drain outlet below valve H andan outlet between said valves which connects with the pipe discharginginto the tank; said lever depressing valve G when the Water in the tankis low, and raising valve H when the Water in the tank is too high, asset forth.

3. The combination with a tank, and an inlet pipe or supply pipe, of afloat, an arm depending therefrom, an L-shaped lever to which the saidarm is connected, a valve G closing the inlet passage a sleeve arisingtherefrom, a valve [-1 closing a drain outlet, a spindle arisingtherefrom which passes through and to a point above the said stem andhaving its upper end slit longitudinally and nut screwed onto the upperend of the same, an expansion spring placed between and pressing inopposite directions against said valves, and a suitable vertical hollowcasting within which said valves are housed having a lateral inlet abovethe valve G, a lateral outlet connected to the supply leading to anddischarging into the tank coming between said valves, anda drain outletbelow valve H, said lever being L-shaped and having its horizontal armentering the slit in the upper end of the spindle and lifting saidspindle when said lever is moved in one direction and depressing saidsleeve stem when moved in the opposite direction.
